If every model in a unit has this ability, then each time a ranged attack is made against it, subtract 1 from that attack’s Hit roll.

Unless part of an Attached unit, this unit can only be selected as the target of a ranged attack if the attacking model is within 12".

Some units have ‘Scouts x"’ listed in their abilities. If every model in a unit has this ability, then at the start of the first battle round, before the first turn begins, it can make a Normal move of up to x", with the exception that, while making that move, the distance moved by each model in that unit can be greater than that model's Move characteristic, as long as it is not greater than x". 

DEDICATED TRANSPORT models can make use of any Scouts x" ability listed in their abilities, or a Scouts x" ability that a unit that starts the battle embarked within that DEDICATED TRANSPORT  model has (provided only models with this ability are embarked within that Dedicated Transport model), regardless of how that embarked unit gained this ability (e.g. listed in their abilities, conferred by an Enhancement or by an attached Character, etc.). 

A unit that moves using this ability must end that move more than 9" horizontally away from all enemy models. If both players have units that can do this, the player who is taking the first turn moves their units first.
